The story is still being worked on, I think. It's "released" as in you are able to download the game lol. I've been keeping track of the release dates, and initially I predicted a public release sometime early September, but it seems the dev has been rather busy with many other things (and some other issues), so I say give it a wait and hope chapter releases by the end of this year. So if you don't wanna be constantly, I would suggest checking just once / month or checking again later this year.
